Intro is the introductory level of the Interchange Third Edition series. It is designed for beginning students needing a thorough, slow-paced presentation of basic functions, grammar structures, and vocabulary. Intro is based on the principle that low-level learning does not equal low-level thinking. Topics such as clothing and fashion, sports and hobbies, food and diet, and holidays and customs are presented in unique ways using interesting real-life information. Each Student’s Book contains 16 teaching units, frequent Progress Checks that allow students to assess and monitor their own learning, and a listening self-study section. As with the other levels of Interchange Third Edition, a complete set of ancillaries is available to make classes productive, varied, and fun.
